In Wednesday’s New York Times, I write about a growing movement to repurpose farmland and toxic waste sites for big renewable energy projects:

LEMOORE, Calif. — Thousands of acres of farmland here in the San Joaquin Valley have been removed from agricultural production, largely because the once fertile land is contaminated by salt buildup from years of irrigation.

But large swaths of those dry fields could have a valuable new use in their future — making electricity.

Farmers and officials at Westlands Water District, a public agency that supplies water to farms in the valley, have agreed to provide land for what would be one of the world’s largest solar energy complexes, to be built on 30,000 acres.

At peak output, the proposed Westlands Solar Park would generate as much electricity as several big nuclear power plants.

Unlike some renewable energy projects blocked by objections that they would despoil the landscape, this one has the support of environmentalists.

The San Joaquin initiative is in the vanguard of a new approach to locating renewable energy projects: putting them on polluted or previously used land. The Westlands project has won the backing of groups that have opposed building big solar projects in the Mojave Desert and have fought Westlands for decades over the district’s water use. Landowners and regulators are on board, too.

“It’s about as perfect a place as you’re going to find in the state of California for a solar project like this,” said Carl Zichella, who until late July was the Sierra Club’s Western renewable programs director. “There’s virtually zero wildlife impact here because the land has been farmed continuously for such a long time and you have proximity to transmission, infrastructure and markets.”

Recycling contaminated or otherwise disturbed land into green energy projects could help avoid disputes when developers seek to build sprawling arrays of solar collectors and wind turbines in pristine areas, where they can affect wildlife and water supplies.

The United States Environmental Protection Agency and the National Renewable Energy Laboratory, for instance, are evaluating a dozen landfills and toxic waste sites for wind farms or solar power plants. In Arizona, the Bureau of Land Management has begun a program to repurpose landfills and abandoned mines for renewable energy.

In Southern California, the Los Angeles Department of Water and Power has proposed building a 5,000-megawatt solar array complex, part of which would cover portions of the dry bed of Owens Lake, which was drained when the city began diverting water from the Owens Valley in 1913. Having already spent more than $500 million to control the intense dust storms that sweep off the lake, the agency hopes solar panels can hold down the dust while generating clean electricity for the utility. A small pilot project will help determine if solar panels can withstand high winds and dust.

“Nothing about this is simple, but it’s worth doing,” Austin Beutner, the department’s interim general manager, said of the pilot program.

All of the projects are in early stages of development, and many obstacles remain. But the support they’ve garnered from landowners, regulators and environmentalists has attracted the interest of big solar developers such as SunPower and First Solar as well as utilities under pressure to meet aggressive renewable energy mandates.

Those targets have become harder to reach as the sunniest undeveloped land is put off limits.

Last December, Senator Dianne Feinstein, Democrat of California, introduced legislation to protect nearly a million acres of the Mojave Desert from renewable energy development.

But the senator’s bill also includes tax incentives for developers who build renewable energy projects on disturbed lands.

For Westlands farmers, the promise of the solar project is not clean electricity, but the additional water allocations they will get if some land is no longer used for farming.

“Westlands’ water supply has been chronically short over the past 18 years, so one of the things we’ve tried to do to balance supply and demand is to take land out of production,” said Thomas W. Birmingham, general manager of the water district, which acquired 100,000 acres and removed the land from most agricultural production. “The conversion of district-owned lands into areas that can generate electricity will help to reduce the cost of providing water to our farmers.”

In my new Green State column on Grist, I attend President Obama’s speech at a Silicon Valley solar panel factory:

Silicon Valley in the Internet age has not made for great presidential photo ops. The Valley’s computer-chip factories were off-shored decades ago and (Google excepted) the software giants that supplanted hardware companies just didn’t have the same pizzazz — T-shirted geeks writing code can’t compete with guys and gals in bunny suits tending big futuristic machines.

The rise of green tech has changed all that. The Valley is back in the business of building stuff — solar panels, electric cars, fuel cells, and various energy efficient widgets and gadgets.

And so when President Obama’s helicopter landed Wednesday morning at Solyndra, a solar module maker, a television-ready tableau awaited — a huge American flag hung in an unfinished factory, shiny high-tech thin-film solar panels were on display and workers in hard hats mingled with an audience of some 200 engineers, scientists, venture capitalists, and California’s patron saint of green tech PR events, Governor Arnold Schwarzenegger.

“We’ve got to go back to making things. We’ve got to go back to exports. We’ve got to go back to innovation,” said Obama on Wednesday in Fremont as Solyndra employees snapped photos with their iPhones.

“The true engine of economic growth will always be companies like Solyndra, will always be America’s businesses,” he continued. “But that doesn’t mean the government can just sit on the sidelines. Government still has the responsibility to help create the conditions in which students can gain an education so they can work at Solyndra, and entrepreneurs can get financing so they can start a company, and new industries can take hold.”

It’s an apt choice of words, for the fortunes of green tech startups like Solyndra have become entwined with the government as the Obama administration attempts to jumpstart a transition to a clean energy economy. The sprawling solar module plant we’re standing in — its construction is employing 3,000 workers — is being financed thanks in large part to a $535 million loan guarantee the Department of Energy granted to Solyndra last year.

In Sunday’s Los Angeles Times, I write about how the rise of green technology is changing the way Silicon Valley venture capitalists do business:

Silicon Valley venture capitalists have always been about inventing the future — taking a wild idea, nurturing it with cash and creativity and giving birth to new products, companies and industries we once couldn’t imagine and now can’t conceive of living without: the Web, Google, the iPhone, Twitter.

But as green technology becomes the latest tech wave to break from the nation’s entrepreneurial epicenter, it’s now all about companies reinventing the past. Solar power companies, electric car start-ups and algae biofuel ventures aim to remake century-old trillion-dollar industries on a global scale.

Venture capitalists poured $4 billion into green-tech start-ups in 2008 — nearly 40% of all tech investments in the U.S., according to a survey by PricewaterhouseCoopers. Green-tech investment plunged in the first half of 2009 to $513 million as the recession dragged on, but there are signs of a rebound: Silicon Valley’s Khosla Ventures announced this month that it had raised $1.1 billion — the biggest first-time fund in a decade — that would be largely devoted to investing in green-tech start-ups, many in Southern California.

But green-tech companies face unique challenges, including global markets, tough technological hurdles and a future shaped by government incentives and regulatory policy. Those challenges are changing the game on Sand Hill Road.

“If you’re starting a Web 2.0 company, your basic needs are personnel and servers — there is no physical product, no manufacturing capacity, no inventory, no steel in the ground,” VantagePoint’s Salzman said, referring to software-based companies that provide services over the Internet.

Clean energy jobs grew 9.1% over the past decade and now number 770,000 as the green tech economy makes inroads in every U.S. state and outstrips conventional job creation, according to a new study released Wednesday by The Pew Charitable Trusts.

Non-green energy jobs, in contrast, grew by 3.7% between 1998 and 2007. The traditional fossil fuel industry employed 1.27 million workers in 2007.

Pew worked with California research firm Collaborative Economics to conduct an actual count of 68,200 businesses engaged in its definition of the clean energy economy — activity that “generates jobs, businesses and investments while expanding clean energy production, increasing energy efficiency, reducing greenhouse gas emissions, waste and pollution, and conserving water and other natural resources.”

“Americans are struggling to get a sense of the nation’s economic future,” Lori Grange, interim deputy director of the Pew Center on the States, said on a conference call Wednesday morning. “The nation’s clean energy economy is poised for explosive growth.”

“It just isn’t California,” she added. “Every state has a piece of the clean energy economy.”

Nevertheless, California remains a clean-energy unto itself and boasted 125,390 jobs generated by 10,209 green businesses in 2007. The Golden State, not surprisingly, attracted $6.6 billion in venture capital funding between 2006 and 2008, six times the amount captured by the runner-up, Massachusetts. Startups focused on clean energy and energy efficiency scored 80% of venture capital investments. California also led in clean energy patents, with 1,401 granted between 1998 and 2007 compared to New York’s 909.

California, however, is getting a run for its money from Oregon, Colorado and other states. Oregon had one of the fastest rates of clean energy job creation and those jobs accounted for the highest percentage of overall employment compared to other states — between .82% and 1.02%.

And Texas, for instance, is the world’s sixth-largest producer of wind energy, Pew researchers said.

The report’s patent numbers offer one indication of where the clean energy economy is headed. Between 1999 and 2008, batteries accounted for 46.6% of the patents while fuel cells took 25.6%. Solar had 8.7% of all clean energy patents and wind had 5%. However, the growth rate in battery patents fell 33% between 1999 and 2008 while fuel cell patents jumped 96% and hybrid system patents grew 147%. Solar patents fell 15% as wind patents grew 155%.

The average annual salaries for clean energy jobs ranged from $21,000 to $111,000, according to the Pew report.

State policies requiring renewable energy production and energy efficiency measures have played a significant role in driving green energy job growth, the Pew authors said. A map showing regions with the biggest green job growth correlate with a map of states with the strongest renewable energy policies.

The solar-cell maker came out of nowhere last year to score a deal with utility PG&E to build the world’s largest photovolaic power plant, a 550-megawatt monster that would cover some 9 1/2 square miles on California’s central coast. OptiSolar subsequently began construction of a factory in Sacramento to produce the thousands of thin-film solar panels needed for the project. Then the economy tanked and as financing dried up, OptiSolar laid off half its workforce – some 300 employees – and halted construction of the Sacramento facility.

With a Colorado solar company executive joining President Barack Obama as he signed the $787 billion stimulus legislation into law Tuesday at a solar-powered museum in Denver, OptiSolar and other renewable energy companies stalled by the financial crisis may see their fortunes revive. The package allows builders of big renewable energy projects to apply for a government cash grant to cover 30% of construction costs in lieu of claiming a 30% investment tax credit. A dearth of investors who finance solar power plants and wind farms in exchange for the tax credits has put in jeopardy green energy projects planned for the desert Southwest and the Great Plains. The cash grant would shave about $300 million off the projected $1 billion price tag for OptiSolar’s Topaz Solar Farm.

The stimulus package also includes $2.3 billion to fund a 30% manufacturing tax credit for equipment used to make components for green energy projects, a provision OptiSolar can tap to help finance its solar cell factories. And the company may be able to take advantage of the legislation’s government loan guarantees for large renewable energy projects.

“It will lower the cost of the factory we’re building in Sacramento and make it easier to attract financing,” OptiSolar spokesman Alan Bernheimer told Green Wombat, noting the company’s priority is to complete the facility and begin production of solar panels. “The factory is more than shovel ready – our shovels are hanging on the wall where we put them when we had stop work in November.” (OptiSolar currently manufactures solar modules at its Hayward, Calif., plant.)

Fred Morse, senior adviser to Spanish solar energy giant Abengoa, says the stimulus package puts back on track a $1 billion, 280-megawatt solar thermal power plant the company will build outside Phoenix to produce electricity for utility Arizona Public Service. “With the stimulus bill we’re very confident we’ll be able to finance the project,” says Morse. He says Abengoa expects to use the government loan guarantees to obtain debt financing to fund construction of the project and then apply for the 30% cash refund. “I think the entire industry is very optimistic that these two aspects of the stimulus package, the grants and the temporary loan guarantees, should allow a lot of projects to be built.”

Mark McLanahan, senior vice president of corporate development for MMA Renewable Ventures, agrees. “I expect the government grants to attract new investors,” says McLanahan, whose San Francisco firm finances and owns commercial and utility-scale solar projects.

There are some strings attached, though.

To qualify for the cash grants, developers need to start shoveling dirt by Dec. 31, 2010. That means only a handful of big solar thermal power plants planned for California, for instance, are likely to make it through a complicated two-year licensing process in time to break ground by the deadline. One of those could be the first phase of BrightSource Energy’s 400-megawatt Ivanpah power plant on the California-Nevada border. But BrightSource’s biggest projects, part of a 1,300 megawatt deal signed with Southern California Edison (EIX) last week, won’t start coming online until 2013 at the earliest.

Another Big Solar project, Stirling Energy Systems’ 750-megawatt solar dish farm for San Diego Gas & Electric (SRE), will be racing to meet the 2010 deadline. The project is in the middle of a long environmental review by the California Energy Commission and the U.S. Bureau of Land Management which currently is scheduled to stretch into 2010.

SolarReserve CEO Terry Murphy says his Santa Monica-based startup has a couple of solar power plant projects in the works that should be able to take advantage of the stimulus provisions. “The likelihood of us being able to close on a financial deal has increased,” Murphy says.

Solar analyst Nathan Bullard of research firm New Energy Finance expects the stimulus package to prompt a push for large photovoltaic power projects. That’s because in California such solar farms – which essentially take rooftop solar panels and mount them in huge arrays on the ground – do not need approval from the California Energy Commission and can be built relatively quickly.

That’s good news for companies like thin-film solar cell maker First Solar (FSLR), which builds smaller scale photovoltaic power plants, and SunPower (SPWRA), which has a long-term contract with PG&E (PCG) for the electricity generated from a planned 250-megawatt PV solar farm to be built near OptiSolar’s project.

“It’s great for PV because you can definitely can get construction done by the end of 2010,” says Bullard. “It’s also good news for smaller and mid-sized developers who couldn’t access tax-equity financing.”

The catch, however, is that renewable energy companies still must raise money from investors in a credit-crunched market to cover construction costs, as the government doesn’t pay out the cash until 60 days after a solar power plant or wind farm goes online. And as McLanahan points out, the cost of raising capital from private equity investors is typically higher and will add to the cost of renewable energy projects. Those costs will only rise if the government is late in paying out refunds.

MMA Renewable finances large commercial arrays and solar power plants and then sells the electricity under long-term contracts to customers who host the solar systems. The loan guarantee provision of the stimulus legislation will help secure financing from investors skittish that some of MMA Renewable’s customers may default on their agreements, according to McLanahan.

The wind industry also stands to gain from the stimulus package through a three-year extension of the production tax credit for generating renewable electricity as well as the government cash grants and manufacturing tax credit. Despite a record year for wind farm construction in 2008, projects have come to a standstill in recent months as the financial crisis froze development and forced the European-dominated industry to lay off workers.

“I think it’s good down payment on what needs to happen,” says Doug Pertz, CEO of Clipper Windpower, one of two U.S. wind turbine makers. “A lot more needs to be done but I think this will start to bring a lot of people back into the marketplace.”

The Mediterranean island nation of Malta on Wednesday unveiled a deal with IBM to build a “smart utility” system that will digitize the country’s electricity grid and water system.

Granted, Malta is a microstate with a population of 403,500 (smaller than Sacramento; bigger than Iceland). But the world — and utility infrastructure giants like General Electric (GE) — will be watching closely. Not only is Malta the first country to green its national grid but it will also serve as a test case for whether integrating so-called smart technologies into both electricity and water systems can help mitigate the increasing deleterious effects of global warming on the island.

As with other island states, power and water are intricately linked on Malta. All of the archipelago’s electricity is generated from imported fuel oil while the country depends on energy-intensive desalinization plants for half its water supply. Meanwhile, rising sea levels threaten its underground freshwater supplies.

“About 55% of the cost of water on Malta is related to electricity – it’s a pretty staggering amount,” Guido Bartels, general manager of IBM’s Global Energy & Utilities Industry division, told Green Wombat from Malta on Tuesday.

So how can digitizing the grid help? IBM (IBM) and its partners will replace Malta’s 250,000 utility meters with interactive versions that will allow Malta’s electric utility, Enemalta, to monitor electricity use in real-time and set variable rates that reward customers that cut their power consumption. As part of the $91 million (€70 million) project, a sensor network will be deployed on the grid – along transmission lines, substations and other infrastructure – to provide information that will let the utility more efficiently manage electricity distribution and detect potential problems. IBM will provide the software that will aggregate and analyze all that data so Enemalta can identify opportunities to reduce costs – and emissions from Malta’s carbon-intensive power plants. (For an excellent primer on smart grids, see Earth2Tech editor Katie Fehrenbacher’s recent story.)

A sensor network will also be installed on the water system for Malta’s Water Services Corporation. “They’ll indicate where there is water leakage and provide better information about the water network,” says Robert Aguilera, IBM’s lead executive for the Malta project, which is set to be completed in 2012. “The information that will be collected by the system will allow the government to make decisions on how to save money on water and electricity consumption.”

Cutting the volume of water that must be desalinated would, of course, reduce electricity use in the 122-square-mile (316-square-kilometer) nation.

With the U.S. Congress debating an economic stimulus package that includes tens of billions of dollars for greening the power grid, IBM sees smart grid-related technologies as a $126 billion market opportunity in 2009. That’s because what’s happening in Malta today will likely be the future elsewhere – no country is an island when it comes to climate change. Rising electricity prices and water shortages are afflicting regions stretching from Australia to Africa to California.

IBM spokeswoman Emily Horn says Big Blue has not yet publicly identified which companies will be providing the smart meters, software and other services for the Malta grid project.

Malta’s greenhouse gas emissions are expected to rise 62% above 1990 levels by 2012, according to the European Environment Agency, and as a member of the European Union the country will be under pressure to cut its carbon. A smart energy grid will help but Malta, like Hawaii and other island states, will have to start replacing carbon-intensive fuel oil with renewable energy.

The island could present opportunities for other types of smart networks. According to the Maltese government, Malta has the second-highest concentration of cars in the world, with 660 vehicles per square kilometer. That also contributes to the country’s dependence on imported oil and its greenhouse gas emissions.

Given that Silicon Valley company Better Place has described islands as the ideal location to install its electric car charging infrastructure, perhaps CEO Shai Agassi should be looking at adding Malta to the list of countries that have signed deals with the startup.

The numbers are in, and as expected 2008 set a record year for the worldwide wind industry as new wind farms generating a total of 27,000 megawatts of greenhouse gas-free electricity came online, according to the Global Wind Energy Council.

The quick-click headline was that the United States overtook the world’s green superpower, Germany, by installing 8,358 megawatts in 2008 – a 50% jump from the previous year and enough wind energy to power two million American homes. But the big story this year will be China’s rapid emergence as the next global wind power.

China last year doubled its wind energy capacity – for the fourth straight year – adding 6,300 megawatts of new electricity generation for a total capacity of 12,210 megawatts. A third of the world’s new wind capacity last year was installed in Asia, with China accounting for 73% of that power. China reached its 2010 target of generating 5,000 megawatts of wind-powered electricity in 2007 and is expected to hit its 2030 goal of 30,000 megawatts years early.

“In 2009, new installed capacity is expected to nearly double again, which will be one third or more of the world’s total new installed capacity for the year,” Li Junfeng, Secretary General of the Chinese Renewable Energy Industry Association, said in a statement.

Of course, 30,000 megawatts of wind is but a flicker in a country with more than 300,000 megawatts of coal-fired energy online but it’s huge by world standards and has spawned both a burgeoning domestic wind industry and growing investment by overseas companies. Denmark’s Vestas, the world’s largest turbine maker, will open its fifth factory in China this year and it received orders for another 200 megawatts’ worth of turbines at the end of 2008. General Electric (GE), one of only two U.S. turbine makers, also operates a factory in China and in January the company announced a joint venture with China’s A-Power Energy Generation to make turbine gearboxes. In a separate deal with A-Power, GE will supply the company with 900 turbine gearboxes starting next year.

As the financial crisis slows growth in the U.S. and Europe, India is another potential wind power. It ended 2008 with 9,645 megawatts of wind energy and added more capacity that year – 1,800 megawatts – than former world leaders Germany and Spain. Indian turbine maker Suzlon also has been moving onto European turf, relocating its international headquarters to Denmark and acquiring German turbine manufacturer REPower.
